WILLIAM WRIGHT, OF MANCHESTER, ENGLAND.

WINDOW-FASTENER.

SPECIFICATION forming part of Letters Patent No. 601,090, dated March 22, 1898. Application filed December r7, 1897. Serial No. 661,068. (No model.) Patented in England May 11, 1826, No. 9,952.

To a/ZZ whom t may concern: I

Be it known that I,WILLIAM WRIGHT,a subject of the Queen of Great Britain, residing at Gorton, Manchester, in the county of Lancaster, England,have'invented new and useful Improved Fastenings Applicable to Railway- Carriage and other Windows and the Like, (for which I have obtained British Patent No. 9,952, dated May 1l, 1896,) of which the following is a specification.

This invention consists of a simple appli- Y ance to be adapted to railway-carriage and other windows and the like for the purpose of enabling the same to be raised and lowered and fixed in any desired intermediateposition.

The nature of the said invention and the i manner in which the same is to be performed or carried into practical effect will be readily understood on reference to the annexed sheet of drawings and the following explanation l thereof. j

ytermediate positions between the two.

The invention is applicable both to the top rail of a sash-window-such, for example,as are used for the doors of carriages-and also to the bottom rail of saloon-windows.

Figure l, on Sheet 1 of the annexed drawings, is an elevation, Fig. 2 a longitudinal section, and Fig. 3 a transverse section, of my improved apparatus as applied to the top bar of a sash-window such as are fitted in the doors of railway or other carriages. YFigs. 4 and 4X show detached parts, hereinafter described; and Fig. 6 shows the'apparatus applied to the bottom rail of a sash which is not lowered into a casing. OnrSheet 2 Figs. 5 and 5X show the application of my invention to the upper sash of an ordinary sash-window.

The invention consists principally of two horizontal sliding bolts a and b, the outer ends of which project through openings formedin the metal casing c, one at each side near to the top of the sliding window-sash d, (the upperpart of which only is shown.) f The outer ends of these bolts a and bare beveled at the top, so as to lock into suitable recesses formed in the fixed frame or stile at each side near to the top or bottom and also at in- The inner ends of these sliding bolts a and b are bent so as to overlap and are provided with teeth or projections e, which interlock with other teeth or projections formed on a central boss f,'which is so 'mounted as to revolve in holes or bearings in the metallic casing c of the apparatus. (See also enlarged detached view of these parts, Figs. 4 and 4X.) 'The projection ff on the boss f coming against the fixed stop fx prevents the boss from rocking too far.

The boss f is fitted with a handle o r thumbpiece g, projecting inside the door of the carriage, and also with a similar one outside, by rocking either of which the boss f can be turned partially, so as to withdraw the sliding bolts a and h simultaneously into the casing c and to release the sash-window and allow it to be lowered or raised to the position required.

The two sliding bolts ct and b are each fitted with a coiled spring h or other suitable spring or springs having a constant tendency to thrust or pull the bolts outward whenever the handle or thumb-piece g is released.

I prefer to make the metallic casing @which incloses the apparatus,of a piece of sheet metal bent into an inverted-trough shape, (see Fig. 3,) so as to be light and capable of being fitted onto the sash without cutting away the woodwork, the parts ax, carrying the movable portions of the apparatus, being xed therein by screws or riveted.

The upper side of the projecting end of each bolt a and b is beveled or rounded like an ordinary door-catch, so that the window can be raised without turning the thumb-piece or handle g, and when the bolts a and b come opposite to the holes in the iixed frame or stile they will be shot outward by the spring or springs and hold the sash in position.

It is only when the sash is to be lowered that the thumb-piece or handle gis required to be turned; but the same knob also serves to raise the window-sash.

When the invention is applied to the top sash of an ordinary window, I employ a short levert' in place of the thumb-piece g, which hangs down at an angle when the bolts are shot, as shown at Figs. 5 and 5X, Sheet 2. To this lever I attach (by a ring or otherwise) a cord 7c, and I make the sash-weights heavier than the sash, so that their tendency is to keep the sash always at the top,and the springbolts b will secure it in that position. When IOO must be pulled straight down, the iirst eiect of which will be to cause the lever 'L' to rock and release the bolts u, and b, and as the pull on the cord is continued it will pull the sash down. On releasing the cord the spring-bolts will iix it. To raise the sash, pull the levert' back into the perpendicular position by the cord 7a and hold it in that position as the weights raise up the sash. On releasing the cord k the spring-bolts a and h will be shot out and x the same.

To adapt this improved apparatus to sashwindows which do not fall down into a casing-such, for example, as the side windows of saloon-carriages-all that is necessary is to bevel o the projecting ends of the bolts in the opposite direction and to turn the apparatus upside down and to fit the same undern eath'the bottom rail of the sash, as shown at Fig. 6. rl`he improved fastening is also obviously applicable to sliding panels and the like.

I claim as my invention- An improved fastening applicable for raising, lowering, sliding, and iXing railway-carriage and other windows, sliding panels and the like consisting in the combination with a hollow metal casing, adapted to be iittcd toy the top or bottom rail of the sash or the like, of two sliding bolts thrown outward by a spring or springs and capable of being withdrawn by partially turning an external thumbpiece, lever or handle fitted to a central boss having teeth or projections gearing With teeth or projections on the inner ends of the said sliding bolts, the said thumb piece, lever or handle being also adapted to be used for raising and lowering or otherwise sliding the window-sash or the like, when the bolts are withdrawn, substantially as hereinbefore described.

In testimony whereof I have signed my name to this speciiication in the presence of two subscribing witnesses.

VILLIAM XVRIGIIT.
